Ladder Hoist and Cart System

The present application relates in general to tool carrying systems. In particular, the present application related to carrying system.

It is common that buildings contain air conditioning, heating, and refrigeration equipment outside on top of the roof of the buildings themselves. Also, not every building has an easy access to allow users, such as commercial and industrial technicians, to get up onto the roof. Some have stairs, externally located building side ladders, internal building ladders that lead up through roof hatches, and some have no roof access stairs or ladders at all. This creates the present problem when the equipment on the roof needs maintenance or repair and the tools and equipment needed to repair them have to be physically transported up onto the roof and to the equipment. There might also be situations where firefighters, paramedics, police, or other individuals might need to bring equipment onto the roof as well and they will face the same hardships. The overall safety and physical strain put on the user when getting the tools and equipment up onto and off of the top of the roof and to the equipment is the main concern here. At the moment with the prior art, a user can only get the equipment up onto and off of the roof of a building by either dangerously single handedly carrying the equipment up and down the ladders and stairs of a building, or by dangerously tying a rope to the equipment with no known or secure place to connect the rope to on the roof.

At times an individual user will have to take multiple trips up and down ladders or stairs given the large number of tools and other equipment needed in order to repair this type of equipment on roofs. This creates an even more significant amount of danger and physical stress to the user as the individual has to climb and descend the ladder or stairs multiple times while carrying the heavy equipment. The strain comes from the individual user climbing the ladder with heavy equipment and with bringing the heavy equipment to the location itself. Individual users will typically use one hand to carry their tools or bags from their vehicle all the way up the ladder which leaves an uneven strain on the individual. This puts more strain on one side of the body over the other and the individual will deal with pain over time because of this. Also, not every roof has locations where a user can safely and securely attach a rope to the roof and the object they wish to hoist. Without this security there is a chance the objects might not make it onto the roof and could become undone in transit which could be catastrophic.

The safety and physical stress of the individuals while working on these projects should be preserved but the current method of carrying up the equipment as the person single handedly goes up a ladder or stairs, or roping up the heavy equipment with no known secure place to connect a rope or rope clip to, and then when on the roof having to hand carry all the equipment and tools to the unit does not preserve this. There have been some improvements to this by using ropes or hoisting systems to lift the equipment as this will decrease the safety risk. However, there are still numerous concerns on the safety and physical strain that is put on the individuals in this work.

Although there are some methods of carrying equipment to job sites that require the use of ladders and multiple dollies, many shortcomings still remain.

While the assembly of the present application is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular embodiment disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present application as defined by the appended claims.

Illustrative embodiments of the barrier film with features including mobility, adjustability, adaptability, and unhindered dispensing are provided below.

The embodiments described in the following paragraphs are configured for compatibility and interchangeability with each other, although many components are illustrated in individual embodiments for ease of description. It should be appreciated that any combination of the herein described elements may be used while maintaining the intended form of the present invention.

Referring now toin the drawings, a building ladder hoistis illustrated according to a preferred embodiment of the present invention. The structure of building ladder hoistis split between removable dolly carrier/casingand winch casing.shows that removable dolly carrier/casingcomprises side walls, top plate, side supports, dolly base, dolly side wall, segmented dolly front wall, support tab, fasteners, supports, supports slot, handle, handle bars, handle supports, wheels, axles, and security strap.shows that the winch casingcomprises side plate, fastener pin, end walls, base plate, side supports, winch strap, winch axle, main winch gear, winch outer plate, winch base, winch support bar, outer winch gear, rotational security bar, winch handle, upper top plate, lower top plate, support box, axle fastener, inner winch gear, winch handle tab base, winch handle tab, boom support bar, boom safety stop fasteners, boom, winch handle bar, and boom security tab.shows how removable dolly carrier/casingand winch casingwill be enjoined together in a way that will be easy for an individual to tow building ladder hoistin its entirety. It is important that an individual will be able to swiftly and efficiently set up this equipment which is why winch casingis designed to be easily disengaged from removable dolly carrier/casing. This allows the user to slide winch casingoff of carrier casing, which allows the user to easily and quickly get the dolly carrier/casingand straps out of the way so winch hoistcan be easily installed on a building ladder.

Referring now also toin the drawings, the back of building ladder hoistis illustrated. As shown in, building ladder hoistfurther comprises padded back, padded replaceable straps, adjustment tabs, strap buckle housing, strap buckle insert, security strap, security strap buckle housing, and strap buckle insert.also provides a back view of side walls, top plate, support box, dolly base, fasteners, handle, handle bar, handle supports, and upper top plate.

Padded backis attached directly to the back of side walls. Padded backsupports the user while they are wearing the carrier and makes it easier for them to carry it around for longer periods of time. Padded backis secured to the back of side wallsby back cushion fastenerswhich can be seen in. Connected to the top of padded backare two padded replaceable strapswhich are attached to the upper left and right side of padded back. Padded strapsallow the user to carry building ladder hoiston their shoulders which will let users carry it for longer periods and experience less fatigue when having to go up building ladders, extension ladders, and stairs. Also, strapsbeing replaceable will allow the user to change them out if they become worn down or if the user desires straps that have more cushion. Padded replaceable strapscan also be tightened to fit the body of the user by using adjustment tab. Adjustment tabuses the extra lengths of the straps to either make strapstighter or looser on the user which will allow the user to set it to where it fits best on them so it's secured and comfortable.

Strap buckle housingis found on the left padded strapwhen looking at the back of building ladder hoistand strap buckle insertis on the right padded strap. Buckle insertwill be inserted into buckle housingto secure the two padded strapstogether. When secured in this fashion, the straps will not be able to slide off the user during movement. Security strapprovides a strap which holds the wide padded backpack straps up in place and keeps them high and tight and out of the way so they don't drag the ground or get damaged when not in use, storing, or towing building ladder hoist. Security strapis attached to the sides of side wallsand strapbuckles over padded strapswhen securing the straps to the carrier using security strap buckle housingand security strap buckle insert. Security strapis attached to end wallsby security strap fastenerwhich can be seen in, security strapskeep padded strapshigh and tightly secured to the carrier when they are not in use.

Referring now also toin the drawings, the sides of winch casingwith the winch boomin the retracted position are depicted. These side views show that winch casingcomprises fasteners, side plate, upper groove, lower groove, fastener pin hole, end walls, base plate, side supports, hoist clip, winch strap, winch axle, winch main gear, winch outer plate, winch base, winch support bar, security bar fastener, rotational security bar, handle, upper top plate, lower top plate, and support box.

Winch casingis rectangular in shape and is formed by end walls, base plate, upper top plateand lower top plate. End wallsare hollow rectangular pillars that extend from the base to the top plates. End wallsmay be made out of metal, wood, plastic, or any other light weight sturdy material. Being light weight, in combination with being hollow, allows winch casingto be as light as possible to make it easy for individuals to carry building ladder hoistwith them. Base plateis L-shaped and connects to the bottom of end walls. Attached to the top of base plate is boom security tab, shown in, which locks on to the end of boomat the winch strap edge supportto keep it secured in the retracted position when not in use. Upper top plateand lower top plateconnect to the top of end wallsand are stacked on top of each other to add extra support and stability for winch casingwhen the winch is in use. Side supportsconnect the side of end wallto the bottom of lower top plateand provide extra support to the top plates while securing them to end wall. Also, on the bottom of lower top plateis support boxwhich is a hollow box that is designed to provide extra support to the top plates while winch casingis in use. All of these supports are instrumental as the winch system may be used to hoist up objects that are larger and heavier than the winch itself. It is important winch casingdoes not break or bend during the process of hoisting it and these supports provide the stability for the system to not buckle under the weight that is being lifted.

Side plateis connected to the side end wallseither by general fastenersor by these structures being welded together. Side plateis, but is not limited to, rectangular in shape and on the section of side platewhich is not connected to end wallare two grooves, upper grooveand lower groove. Upper grooveis nonlinear in shape and extends inward from the side of side platebefore extending upward. Lower groovestarts at the bottom of side plateand extends upward before ending. These grooves are used to allow the user to have a quick and easy way to secure winch casingto a ladder. The reason that upper groovehas its nonlinear shape is that it the notches will catch onto the ladder which will prevent winch casingfrom coming undone during the process. At the upper portion of side platethat is not connected to end wallthere is also fastener pin holewhich, when winch casingand removable dolly carrier/casingare together, fastenerwill be inserted through it in order to secure these two casings together.

also provide a look at the winch system when it is not in use on winch casing. Connecting to the inside walls of end wallsis winch base. Between winch baseare support barswhich provide extra support for the whole system in order to keep it in place. Winch baseis C-shaped with the bottom edge extending further out then the upper edge. Rotational security baris connected to right side of winch baseby security bar fastener. Rotational security baris mostly flat with a tab protruding out from the end of it which the user will pull on to us it. Security baris designed so that a user will be able to pull on the bar in order to stop the gears inside the winch from turning in case the user wants to keep the item they are hoisting in place or if they lose control of the winch and need to stop it. Security baris connected to a support bar between winch basewhich has an outer winch gearattached to one end, as seen in. By pulling on rotational security bar, the support bars will be caught which will prevent outer winch gearfrom turning which will also stop inner winch gear, shown in, which will stop the winch from turning and stopping the entire system.

The winch system is between the two winch basesand connecting both bases is winch axle. Attached to the ends of winch axlebut in-between the two sides of winch baseare two winch outer plates. Axle fastener, as seen in, extends through both outer platesand through axleto secure the winch system to winch base. On the outer side of the left out platethere is winch main gearwhich is the main gear that handleis used to turn to lower and raise winch strap. It is also appreciated that the winch system could be replaced with an electrical winch where a user would be able to lower or raise the winch using an electrical system instead of doing it by hand using handle. The electrical winch may be plugged into local power source on the building or may use batteries or other portable sources of energy for power. Winch strapis stored by being wrapped around winch axlewhen not in use and then winch main gearis turned in order release and lower winch strap. Hoist clipis a connecting loop at the end of winch strapand connecting hook, which can be seen in, is secured through that loop. Connecting hookis used to secure hoist hook, also seen in, to winch strap. Hoist hookis used to attach to objects that the user wishes to hoist up a ladder or up a wall or any other space. Hookhas latchwhich will secure the object in place where it is hooked, this latch will only be openable by putting pressure on it from the outside so any object putting pressure on it from the inside while being hoisted will not open latch.

Referring now also toin the drawings, a perspective side view of building ladder hoistis shown.shows a perspective view of carrier casingand winch casingconfigured together.then shows a view of winch casingbeing unhooked from carrier casingand the two casings being separated from each other in a perspective side view.

Referring now also toin the drawings, a perspective view of removable dolly carrier/casingis shown.shows that removable dolly carrier/casingfurther comprises side walls, top plate, support box, fastener hole, side supports, dolly base, dolly side wall, segmented dolly front wall, support tab, fasteners, side wall supports, back wall supports, boom supports, notch, supports slot, handle, handle bars, upper supports slot, handle bar stoppers, handle supports, wheels, axles, and security strap, security strap fastener, and back cushion fastener.

Side wallsare L-shaped and are connected at the top by top plate, also L-shaped, and then connect at the bottom to dolly base. Side wall supportsare also L-shaped and are on the inside of side wallsand are fastened to these walls in order to provide extra support and stability to the structure. The walls and bases of carrier casingmay be made out of metal, wood, plastic or any other sturdy light weight material. It is important that this material is light weight as the user needs to be able to carry this equipment with them and if it is too heavy that would not be possible. The material also needs to be sturdy in order to not lose its form when in use. Side wallsand top platemay be connected by fastenersor they may be welded together. Both side wallsand top platebeing L-shaped provided extra support and increases the stability of the structure as a whole.

Dolly baseconnects to the bottom of side wallsand may be secured by fastenersor by welding the parts together. On the top of baseand connected to the back part of wide wallsis support boxwhich leaves a space between it and the side of side walls. Support boxis square in shape and is used to support wench casingwhen it is attached to carrier casing. Support boxprovides a platform for parts of wench casingto lean against so that when in movement these parts will not get damaged. Also, support boxfurther provides support for axleas it goes through and is secured in place by support boxwhich maintains the stability of the wheels during movement.

The dolly portion of carrier casingis used in order to tow other objects that the user wishes to bring with them so that way they can keep their hands free while also putting less strain on their bodies. The dolly is formed by dolly base, dolly side walls, and segmented dolly front wall. Dolly side wallsare straight and connect in the back to side wallseither through fasteners or by being welded together. Connected to the sides of side walland dolly side wallis side supportwhich further connects these two ends to secure the parts together and provide extra stability. Side supportmay connect these two side walls either through fasteners or by being welded together. Segmented front wallis segmented into five sections, but is not limited to five and may be segmented into more or less sections. Attached to one of the sections of front wallis support tabwhich can either be fastened to front wallwith fastenersor by being welded to it. Support tabis a square plate which is used in order to support carrier casingin the upright position when it is not in motion.

Connecting over the gap between the side wallsare back wall supports. These supports stretch the gap between side wallsas there is no back wall and provide support for carrier casingwhile also providing a place for boomto lean against when not in use. The lack of a back plate is to make it less weight and supportsare used to provide support and stability of the structure. Attached to the top of back wall supportsare boom supportswhich project out from back wall supports. Boom supportshave a notchin the middle of them which is the same width as boomwhich will keep it secure when not in use. Back wall supportsand boom supportstogether maintain the stability of the winch system when it is not in use and when the user is carting it from location to location. With all the movement involved, without these supports maintaining the system, there is a chance it could be damaged and become too dangerous to use.

At the top of carrier casingis the handle system which allows the user to pull the cart behind them if they are already carrying something on their back or if they just do not desire to carry it. Handleis rectangular in shape and is connected at both ends by handle bars. Handle supportsare used to secure handleto handle barswhile also providing more stability, these sections can be secured together either with fasteners, or by being welded together. Handle barsextend down through upper support slotin top plateand through support slotin the upper most boom support. These slots are just big enough for handle barsto slide through them but not big enough to provide leeway for movement in the horizontal direction so handle barswill be secure in these slots and will only be able to move up or down. Handle bar stoppersare installed at the bottom of handle barsand they are protrusions that stick out from handle barto prevent it from being removed from the slots. These prevent the handle system from being removed from its housing which will allow the user to use it without concern that building ladder hoistwill get loose in transit.

Referring now also toin the drawings, building ladder hoistis shown with the retractable boom in the retracted position with the boom safety stop engaged. These figures show that wench mechanism includes hoist hook, connecting hook, hoist clip, winch strap, winch axle, winch main gear, winch outer plate, winch base, winch support bar, security bar fastener, rotational security bar, handle, axle fastener, winch handle tab base, winch handle tab, security bar spring, rotation stopper, support plate, boom support bar, boom safety stop fastener, boom, winch strap edge support, edge support axle, winch handle bar, winch handle base, winch handle base slot, and hinge. These figures demonstrate how the winch system is attached to boom.

When using the winch system on building ladder hoist, handleis removable to allow for easy storage when not in use. When not in use the handle can be stored between the two winch basesas seen in. Handleis attached on one end to winch handle barwhich extends at an angle. At the end of handle baris winch handle basewhich is a square plate with base slotin the middle of it. On the outside of the right winch basethere are two tabs which are formed by winch handle tab basewhich has winch handle tabprotruding from it. Each handle tab baseconnects to a support barthat has a gear attached to it, so by inserting slotover tab, the user will be able to turn handleto turn the gears of the winch system.

Winch strap edge supportis found at the end of boomand is used in connection with winch strap. Edge supportmay be connected by either fastenersor by being welded to boom. Winch edge supportis separated into three segments, though it may be separated into more or less segments, it has one straight segment which attaches to the sides of boom, it has a tilted slight curved section that goes inward beyond the edge of boomthen finally has another straight section that goes out and ends with a circular edge. Between the final straight segment of edge supportis axlewhich extends between the gap of the two final segments of support. Supportand axleare used as a support for winch strapwhich will extend upward from the winch then go over axlebefore extending back down. This provides extra support and stability for the system when it is being used to hoist an object and it serves as a handle for retrieval of the boom.

Referring now also toin the drawings, a close up view of winch casingwith the boom stop engaged stopping the boom from falling any further.shows a close up of the system fromof how boomextends into the upright position which is comprised of rotation stopper, support plate, boom support bar, boom safety stop fastener, boom, and hinge.

Hingeprovides the main function that allows for boomto rotate between the up and down positions. Hingeis attached to one side of boomand to the underside of lower top plate. Hingemay be attached by fastenersor it may be welded instead. Boom support baris attached to the sides of boomby fastenersand provides support for boomwhile in use. On the other end of boom support bar, support plateis a C-shaped support that attaches to the sides of bar, either by fastenersor by welding. Support barand support plateare designed to provide extra support for boomwhen it is in use in order to make sure the object being hoisted make its securely to its location. Also attached to the side of support barare rotation stopperswhich are either attached by fastenersor by the parts being welded together. Stoppersare U-shaped and are designed to catch boomonce it has extended to a certain point. The side of stopperthat is not fastened to support baris positioned in order to catch onto lower top platewhen it is extended to a certain point which will stop boomfrom extending any further. This limits the range of motion that boomwill be able to rotate which will secure it in place when in use.

Referring now also toin the drawings, a close up view of an alternative embodiment of the boom stop and boom axle on winch casingis shown.shows an alternative embodiment to how the boom extends into position and includes axle support plates, axle housing, axle, axle hole, pin hole, spring, pin release, and pull release pin.

In this alternative embodiment, instead of using hingeto control how boomis retracted, an inside axleis used. Attached to upper top plateare two axle support plateswhich are cube shaped. Support platesare on both sides of axle housingwhich houses and supports axlewhich directly connects to boom. Support platesare used in order to support and secure boomto winch carrier. Axleis designed in order to provide boomwith a range of movement while also being secured inside of housing. Being secured inside of housingwill prevent the user from getting snagged by boomwhen it is in motion as there will not be the crevices between the boomand hingesuch as the ones seen in. Axleis inserted into its housing through axle hole, Axleis also long enough to where a portion of it is in support plateswhich provides extra supports for the system. On the top of the right support plateis pin holewhich provides a location for pinto be inserted through support plateto stop axlein its location which will secure boomwhere it currently is. Pinhas springrunning along it so when pinis inserted the spring will become compressed, and will secure pin in support plateuntil pin releaseis used. Pin releaseis C-shaped and is used to keep springcondensed when pinis inserted. When the user wishes to remove pinfrom support plate, they will disengage releaseto release spring. Once released, pinwill regain its range of movement and can be removed from pin holeallowing the user to modify the angle that boomis set at before locking it in place again.

Referring now also toin the drawings, an individual climbing a building ladder with building ladder hoistis shown. In this figure, building ladder hoistis attached to the back of an individual using back straps.shows how strapswill be used to allow an individual to climb a building ladder hands free while having building ladder hoistattached to their back.

Referring now also toin the drawings, winch carrieris shown attached to a building ladder. One of the important features of winch carrieris being able to securely connect to the rungs of a ladder to allow an individual to hoist up other equipment, tools, or any other object.shows winch carrierbeing securely connected to the rungs of a ladder.then show the step by step process of using the winch system to hoist an object up the ladder and onto the roof.shows hoist armbeing extended out andshows winch strapextending down to allow hookto connect to the object.shows the object hoisted up to the top of the roof andthen shows the boomin the retrieved position and locked into place by boom safety stopso the user can safely and easily remove the equipment. The rotation ability of boomis utilized in this way by being able to rotate boomback into the retrieved position while the object is attached as this will allow the user to not have to reach out over the edge to remove the equipment and instead the object that was hoisted will be at an easy location for the user to grab. This is the main function of building ladder hoistand these figures demonstrate the ease of safely bring equipment, tools, or other objects to the roof of the building.

It should be appreciated that the winch system described above may take on alternative embodiments not shown herein, while maintaining the overall structure of the present invention. For example, instead of a manually operated winch, the winch system may be automated such that the use of a push button operates the winch in raising or lowering an object. Additionally, rather than a handle, the winch could be operated by a user via a drill operation, as many intended operators of the system are likely to have a cordless drill in their possession. In such an embodiment, a cordless drill could be connected to the winch system via a socket, where the drill could then be operated to either raise or lower a desired object associated with the winch system.

Referring now also toin the drawings, this shows an individual wearing alternative building ladder hoistwhile walking. Alternative building ladder hoistis securely attached to the back of the user using back strapsin this figure. By securing alternative building ladder hoistto the back of the user, the user will have both hands free during transit which will allow them to tow other objects with them. This will cut down on the number of trips the user will need to take and lessen the strain on the individual.

Referring now also toin the drawings, a perspective front view of building ladder hoistbeing stored in a truck is depicted. It is important that building ladder hoistbe small and compact so that way it does not take up too much space wherever it is stored.depicts this by showing building ladder hoistbeing compact and stored in a standard storage compartment that could be found on the side of work trucks.

Referring now also toin the drawings, a perspective view of an alternative embodiment of a building ladder hoist is depicted. Alternative building ladder hoistis split between removable carrier casingand winch casing.shows how removable carrier casingand winch casingwill be enjoined together in a way that will be easy for an individual to tow ladder hoistin its entirety. Handle insert, upper insert, and lower insertare used together to secure the two casings together. It is important that an individual will be able to swiftly and efficiently set up this equipment which is why winch casingis designed to be easily disengaged from removable carrier casing. This allows the user to slide winch casingoff of carrier casingso the user can then install alternative building ladder hoiston a building ladder and removable carrier casingand straps are out of the way.

Referring now also toin the drawings, the back of ladder hoistis illustrated. As shown in, ladder hoistfurther comprises padded back, padded replaceable straps, lower adjustment tabs, strap buckle housing, strap buckle insert, security strap, security strap buckle housing, strap buckle insert, padded handle, upper adjustment tabs, and security strap pads.also provides a back view of back wall, top plate, bottom plate, handle insert, side plate, upper groove, handle plates, lower adjustment holes, and side support plate.

Padded backis attached directly to back wall. Padded backsupports the user while they are wearing the carrier and makes it easier for them to carry it around for longer periods of time. Padded backis secured to back wallby back cushion fastenerswhich can be seen in. Connected to the top of padded backare two padded replaceable strapswhich are attached to the upper left and right side of padded back. Padded strapsallow the user to carry ladder hoiston their shoulders which will let users carry it for longer periods and experience less fatigue. Also, strapsbeing replaceable will allow the user to change them out if they become worn down or if the user desires straps that have more cushion. Padded replaceable strapscan also be tightened to fit the body of the user by using lower adjustment taband upper adjustment tab. The adjustment tabs use the extra lengths of the straps to either make strapstighter or looser on the user which will allow the user to set it to where it fits best on them so it's secured and comfortable. Found at the top of padded backis padded handlewhich allows the user to carry ladder hoistin the hand instead of having it strapped to their back.

Strap buckle housingis found on the right padded strapwhen looking at the back of building ladder hoistand strap buckle insertis on the left padded strap. Buckle insertwill be inserted into buckle housingto secure the two padded strapstogether. When secured in this fashion, the straps will not be able to slide off the user during movement. Security strapprovides a strap which holds the wide padded backpack straps up in place and keeps them high and tight and out of the way so they don't drag the ground or get damaged when not in use, storing, or towing ladder hoist. Security strapis attached to back wallsby security strap fastenerswhich can be seen in. Strapbuckles over padded strapswhen securing the straps to the carrier using security strap buckle housingand security strap buckle insert. Attached at both sides at the bottom of padded supportare security strap padswhich extend out from the sides of padded supportand provide padding where security strapwould run so that way the user will not feel the strap directly against them.

Referring now also toin the drawings, the sides of winch casingwith the telescopic winch boomin the retracted position are depicted. These side views show that winch casingcomprises fasteners, side plate, upper groove, lower groove, upper insert hole, lower insert hole, bottom plate, side walls, winch axle fastener, winch base, winch outer plate, winch main gear, winch axle, winch strap, winch support bar, inner winch gear, rotational security bar, upper top plate, lower top plate, handle plate supports, handle plates, lower adjustment holes, upper adjustment holes, and side support plate.

Winch casingis rectangular in shape and is formed by side plates, base plate, side walls, upper top plateand lower top plate. The walls and plates of winch casingmay be made out of metal, wood, plastic, or any other light weight sturdy material. Being light weight, in combination with being hollow, allows winch casingto be as light as possible to make it easy for individuals to carry ladder hoistwith them. Side plateis L-shaped with one end protruding out from the back of ladder hoist. Base plateis also L-shaped and connects to the front of the bottom of side plateand connects to the back of the bottom of side wall. Upper top plateis L-shaped and connects to the top front of side plateand lower top plateis also L-shaped and connects to the front of upper top plateso that the top plates are stacked on top of each other to add extra support and stability for winch casingwhen the winch is in use. Side wallis L-shaped and is next to side plateand extends up from bottom plateup to lower top plate. All of these plates and walls may be connected to each other either through general fasteners, or by being welded together.

The section of side platewhich protrudes out from the back of winch casinghas two grooves, upper grooveand lower groove. Upper grooveis nonlinear in shape and extends inward from the side of side platebefore extending upward. Lower groovestarts at the bottom of side plateand extends upward before ending. These grooves are used to allow the user to have and quick and easy way to secure winch casingto a ladder. The reason that upper groovehas its nonlinear shape is that it the notches will catch onto the ladder which will prevent winch casingfrom coming undone during the process. At the groove locations on side plate, there is also side support platewhich has the same shape as the grooves on it and is connected to side plateto provide extra support for the casing when in use. Found above upper groovethere is upper insert holeand above lower groove there is lower insert hole. Also, when winch casingand removable carrier casingare together, upper insertwill be inserted through insert holeand lower insertwill be inserted through insert holein order to secure these two casings together.

also provide a look at the winch system when it is not in use on winch casing. Connecting to the inside walls of side wallsis winch base. Between the two sides of winch baseare support barswhich provide extra support for the whole system in order to keep it in place. Winch baseis C-shaped with the bottom edge extending further out then the upper edge. Rotational security baris connected to right side of winch base. Rotational security baris mostly flat with a tab protruding out from the end of it which the user will pull on to us it. Security baris designed so that a user will be able to pull on the bar in order to stop the gears inside the winch from turning in case the user wants to keep the item they are hoisting in place or if they lose control of the winch and need to stop it. Security baris connected to a support bar between winch baseand has a small protrusion sticking out it and pointing in towards the gears of the winch. By pulling on rotational security bar, the protrusion will catch on inner winch gear whichwhich will prevent it from turning. By pulling on security bar, the hoist will operate down, and when pushed the hoist will operate up.

The winch system is between winch baseand connecting both sides of this base is winch axlewhich is connected to the base by axle fastener. Attached to the ends of winch axlebut in-between the two sides of winch baseare two winch outer plates. Axle fastenerextends through both outer platesand through axleto secure the winch system to winch base. On the outer side of the left out platethere is winch main gearwhich is the main gear that moves winch strap. Winch strapis stored by being wrapped around winch axlewhen not in use and then winch main gearis turned in order release and lower winch strap. Connected to the top of upper top plateare two handle plate supportswhich extend upward into handle plates. Handle platesare rectangular in shape and end with a curved portion. At the top of handle platesthere are three upper adjustment holesand at the bottom there are four lower adjustment holes. Pin, which can be seen in, can be inserted into one of these holes to adjust the angle that boomwill sit at when in use while also keeping it locked in place there.

Referring now also toin the drawings, the back of winch casingis depicted. Along with what was shown in,shows that winch casing further comprises a hinge, an adjustable boom, a winch handle base, a winch handle fastener, a winch handle bar, a winch handle grip, fastener pins, a winch strap edge support, and a winch strap edge axle. Hingeis connected to the back of upper top plateand allows for adjustable boomto be pulled up into position. Adjustable boomis a rectangular hollow telescoping structure that is used with the wench to hoist items up. Adjustable boomhas extra length stored inside of it and the user can extend the length of boomby removing pinsfrom the side of boomthen inserting them back in once a desired length has been met. Winch baseis attached to the top of boomandshows that on one side of winch basethere is the handle system used to turn the gears and work the wench. This handle system is comprised of the winch handle basewhich is square in shape and is fastened to the side of winch baseby fastener. Handle basethen curves up at an angle before straightening out again to form winch handle barwhich extends out before ending in a curved edge. Winch handle gripis attached perpendicular to the end of handle barand provides a location for the user to crank the handle system to work the winch. At the very end of boomthere is winch strap edge supportwhich is two prongs that extend out from the end of boomand winch strap edge axlespans the gap between these two prongs. Edge supportand axleare used as a pulley system with winch strapto make it easier for the winch system to hoist items so that way the user does not have use as much effort to lift heavy objects.

Referring now also toin the drawings, a perspective view of the carrier casingand winch casingwhen not connected is depicted.shows the general orientation of these two casings in relation to each other. One of the main functions of these two casings is to be easily removed from each other for quick work andshows the orientation between them normally.

Referring now also toin the drawings, a perspective view of carrier casingis depicted. Carrier casingis shown to be comprised of a back wall, top portion, top grooves, a pair of side walls, a bottom portion, bottom grooves, top plate hinge, top plate, top plate grooves, back cushion fashioners, security strap fasteners, upper insert hole, lower insert hole, and general fasteners. The walls and plates of carrier casingmay be made out of metal, wood, plastic, or any other light weight sturdy material. Being light weight, in combination with being hollow, allows winch casingto be as light as possible to make it easy for individuals to carry ladder hoistwith them. All of these plates and walls may be connected to each other either through general fasteners, or by being welded together.

Back wallforms the main structure of carrier casingand is rectangular in shape but has a segmented bottom that is comprised of three straight portions. Attached to the front and top of back wallis top portionwhich is L-shaped. Top portionextends the entire width of back wallalong with extending out from the sides of back wall. Part of top portionprotrudes out from the front of back walland that protruding portion contains two grooveswhich allow handle platesto fit into top portion. Attached to the front and the bottom of back wallis bottom portionwhich is also L-shaped. Bottom portionalso extends the width of back wallas well as extending out from the sides of back wall. The section of bottom portionwhich protrudes out from back wallhas three bottom groovesinstead of the two in top portion and these grooves align with boomand the side walls. The grooves located at the top and bottom section of carrier casinghelp secure the components of winch casingin place so that way during movement there will be a less likely chance of the parts becoming damaged. Extending between top portionand bottom portionare side wallswhich is a rectangular plate which extends the full length between them to help with support.

Attached to the top of top portionis top plate. Top plateis connected to top portionby hingewhich allows for top plateto be moved up and down at will. The reason for this is that top platehas two groovesin it that are aligned with handle plates. So handle plateswill be inserted into place before handle insertis place into one of adjustment holes in it and it will work as another way of securing wench casingto carrier casing. Side wallfurther has upper insert holeand lower insert holewhich, when connected with winch casing, coincide with the insert holes found there and once the inserts are placed in these two casings will be securely connected.
